For two consecutive days, Bitcoins fell late at night. There are many rumors on the Internet, some people say that the exchange joint bankers, institutions, a hanging of retail investors. Others say they are preparing for big organizations to come in one after another. But in any case, retail investors are innocent.
There is no conspiracy at all, and why would bankers and exchanges join forces? Doesn't make any sense. The only reason is that people just selling their bitcoin, that's all. We can stop them from doing that since we are in a free market.
So stop with this whole conspiracy scenario, it all speculation and there's no proof of such actions. Maybe we are really in the oversold regions in the last two months or so and more likely investors just decided to dump and probably go buy when the price is cheap again.
